Emflon® PFR - Kleenpak™ Capsules

Pall Kleenpak™ filters combine the widest available range of filter media with specially designed self-contained assemblies, to satisfy the very highest standards of filtration security and user convenience.

Emflon® PFR Filter Medium

At the heart of every Kleenpak Emflon PFR Capsule filter is a high-performance pleated cartridge, containing proprietary PTFE membrane. The high-strength PTFE membrane is inherently hydrophobic, chemically inert, and designed specifically for removal of contaminating bacteria and viruses. Emflon PFR filters have a microbial removal rating of 0.2 µm in liquids and a particulate removal rating of 0.003 µm in gases. Emflon PFR filters meet the ever-increasing demand for air filters with greater strength and longer life.

Clean and Robust Design

The Kleenpak filter uses well-proven proprietary Pall techniques for filter construction and heat sealing.
  • The highest possible security against filter bypass is ensured, even under conditions of pulsed flow
  • High-strength design allows multiple autoclave cycles for extended use and maximum filter economy
  • Polypropylene outer shell is designed to provide long-term assurance of pressure and temperature ratings
  • A total absence of glues, binder resins and surfactants results in very low filter extractables and extremely clean filtrate

High Quality Standards

Every Pall Kleenpak filter is manufactured to a very high standard of quality assurance and cleanliness, and in accordance to a quality system accredited to ISO 9000.
For pharmaceutical use, the P designation in the part number provides full traceability supported by a certificate of test.

Quality and Bio-Safety

Biological Tests

  • Meets USP Biological Reactivity Test, in vivo for Class VI-121 °C Plastics

Effluent Quality Tests*

  • Meets Cleanliness per USP Particulates in Injectables
  • Non-Fiber-Releasing
  • Non-Pyrogenic per USP Bacterial Endotoxins (< 0.25 EU/mL)
  • Meets Oxidizables and pH per USP Sterile Purified Water

*Per lot sample soak or rinse-up flush aliquots.

Features and Benefits

  • Comprehensive validation assures highest removal efficiency and highest safety margins (validation guide available on request)
  • High flow-rates and low pressure drop allow use of small systems, reducing installation and running costs
  • Robust construction ensure integrity and reliability
  • Long autoclave life and long service offer low-cost filtration
